SPECXFIGATIGN forming part of Letters Patent No 764,049, dated July 5, 1904:.

Application led October 28, 1902.

To all. L11/wm it may concer-71,:

Be it known that I, OLAF N. 'GULDLIN, a citizen of the United States, residing at Fort ,Pi'yayne, in the county of Ailen and State of Jindiana, have invented certain new and useful Improvements in GasVVasliers; and 1de hereby declare the following to be a full, clear, and exact description oi the invention, such as will enable others skilied in the art to which it appertains to Ina-he and use the saine.

This invention relates to apparatus for wash- 'as, and more particularly to improvements the gas-washer described and cinined in lLetters Patent No. 677,865, In the fied by being passed from longitudinal channels through perforated side and crown pla-tes, and thereby caused to escape in numerous small streams through the \vasli-water or ammoniacal liquor. Valuable results l are secured by this method and apparatus: but the flow of liquor over the perforated crownplates is so slow as te permit impurities to deposit and eiog the perforations, thereby decreasing the eiiicieney of the apparatus. Moreover, in said apparatus the circulation oi liquor in the washing-chamber is imperiect, so that the Weak iiquor at the bottoni oi' the chamber is not effectively utilized. in my present invention these deficiencies' in the operation are overcome and increased etticieney secured by previdins,r means for accelerating the flow of liquor over the perforated crown-Mates and insane 'fr "circulating the. ,gh tne Washingn chamber, t @ne weak liquor which has. heretofore iain inactive at and near the bottoni of the chamber is forced. vup and over the perforated crown-piates into Contact with the numerous etres-'zus of outowing' gas, thereby greatly increasing' toe strength oit' the iiquor in srnrnonia and the eiciency of the apparatus. I'Ehe croafaplates are made with numerousper'erations heyingiinciined wings 'or guards serve to deect and direct the slof :ges under pressure forward into .roam of iianor, thereby accelerating its to the discharge uiatingepipe at the nd oi wasang-ehannel. A second Serial No. 129,112. (No model.)

or supply circulating-pipe extends down into the body of the liquor at the front end of each washing-channel and opens at the-upper surface of the perforated crown-plate -for permitting the upward flow of weak liquor and thence into contact with the. streams oi' `gas passing through the crown-plate. l also provide an overlioW-eompartment at the rear end i the washing-chamber for receiving;` surface scum Which may be carried by the circulating` liquor and conducting it o' with the outiowing' liquor.

` rlhe improvements constituting my invention herein will be deiincd in the claims.

The details oi' construction of my improved gas-washing apparatus are illustrated in the accompanying drawings, in which* Figure 1 represents a vertical longitudimil section through the gas-Washer on the line fr 11:, Fig. 2, the section being through one of the washing-channels and one of the frames carrying the perforated plates. Fig. 2 represents a vertical transverse section thereof on the line 1/ y, Fig. 1. Fig. v3 represents a top plan View, partly in horizontal section, showing' the gasinduction channels and the ,gas- Washing channels alternating one with the other. Fig. e represents a plan view, on eularged scale, oi' a part oi' one of the perforated crown-plates. Fig. 5 represents a longitudinal section of the saine on thtA line FigY 4, showing' the deiieeting' wings or guards.

Fig. 6- represents a vertical transverse section on iine zo w, Fig'. 1, through the u usher-box looking toward the right or rear end thereof. Fig. 'i' represents a perspective view of part oi' one ci' the detachabie frames carrying periorated plates.

divirflii The c.

perliorated side and crown plates are prelerahly secured together in trame l), and the whole trarne may be readily detached and removed through the end manholes X for cleaning; or repair. The traine D is constructed ol the lateral longitudinal angleirons d, suitahle end plates u, the transverse bars fl'. the inclined perforated side plates y, and the perlioi'ated crown-piate il. foratod site plates are preferably curved downwart. and ii'n'ard. as shown in Fig. 2,

The pen.

and are secured to flanges u and n oi the end i plates and to the angle-irons d. 'The crown- Aplate is transversely arched, as shown in l' igr. and is secured at its edges to the'angleirons d.

iyeboltsf, havingr screw-threaded lower ends, are passed through openings in l te il and in the cross-bars J" cured hy nuts helow the cross'hars, U l and 2. flpacing` and (,:rown-plate and the crosssold the crown-plate against on the eyebolts. 'Ihn eye provided at their opper ends with T"nich are engaged the hooks ,i or ods l, by means ol whiff nels C. The clamping-rods l have screw threaded upper ends which pass through openings in 'the transverse supporting-hars L. rl`hese bars L rest at their outer ends on shoulders c' at tlie tops of the channelplates C', as shown in Fig. 2. The clampingrods h'. are drawn up tight and securely held in place by nuts applied above and below the.

` hars L, thereby holding' the frames l) against the lower edges c" o'r' the gas-channels lf. It will be understood that by means of the ahove described devices the frames l) may he rcadil y detached for cleaning or repair and can be quickly replaced and secured in operative position. lt is to be noted that the perforated side plates g are curved inward toward and below the washing-channels F, so that the streams or' gas after passing through the plates will more readily rise through the water and he better subjected to the washing and puritying action thereof.

'lhe front end plates Il of the frames ll) are cast witn the supply circulating pipes O, which open ahovc the crownplates, and the rear end plates are cast with the discharge circulating-pipes N, as shown 'in Figs. 1 and 3. The circulating-pipes and (l extend down below the frames l) into the Washing-cham her, so as to produce a better circulation of the whole body of liquor and prevent thunecuniuiation of weak liquor in the bottom ol the box.

The perforated crown-plate Hat the hottoin of cach washingr-channel F is of peculiar and novel construction.l as shown in Figs. 4 and The perforations /i are conveniently .'nade of crescent or segmental shape," as shown, and the portion of metal' which is partly cut out from the openings is bent upward to form inclined wines or guards 1l', which are inclined forward in the direction or' the flow of the liquor. The wingsor guards /l' by being inclined toward the rear end ofthe washingchannel F deflect the streams of gras as they escape through the pert'orations under pres sure toward `the rear end of thel channel.V ',lfhe

streams of gas pass into the current ot' liquor and accelerate its flow toward the discharge end of the channel. rl`he pcrforations and their inclined guards may be of any desired shape; out the curved segmental shape shown oil'ers less resistance to the passin, i5A liquor. The periorations and guards are prelcinhly arranged in' one row to break joints with those in the adjacent row, as shown in Figs. 4l and fl. main liquor-supply channel M is secured transversely across the front end of the washer, shown in Figs. l and 3,v and is provided with un inlet M'. Small dischargepipes m connect said channel M with the washingi-channels i?, as shown in Figs. l and 3. lt will he seen. therefore, that both the circulatie;r liq- 'ii/or risingr thrr'iugh pipe (l and liquor or water from ille outside are supplied lo the iront ends ol' the washing-clia'nnels and 'lis- IOC IIO

charged upon the crown-plate H. The liquor from both sources 1s accelerated 1n its flow by the rising deflected streams of gas passmg all impurities and sedimentary matter are prevented from depositing' and clogging the perforations in the crown-plate. The wings or guards /l will also slightly agitata the liquor, so as to better wash the gas. liquor supplied to the crown-plate H is so accelerated in its flow that it passes in a decided current down through the discharge-pipe N, and thus assists Athe circulation of liquor through the bottoni ofthe chamber, and thence upward through the supply-pipe O into the front end of the washing-chan nel F.

A drain-pipe P,'having a valve p, connects with the middle portion of the bottom of the washingbox and serves for the removal of any tar or other` in'ipurities which may settle in the bottom of the box or for drawing oil all of the liquor when it is desired to clean or repair any of the interior devic s of the box.

An overflow-chamber l is bolted transversely across` the outlet end of the washer and is divided by a horizontal partition-plate q into upper and lower compartments fr and r'. Une or more openings are made in the partition-plate r/ and are screw-threaded to receive the ad '|ustable screw-threaded liquor-overflow pipes s. A hand-hole is made in the upper part of chamber R and is closed .by a tightfitting cover 2f, having suitable fastening devices, as shown in Fig. 1. rlhe overliow-pipe .v will be adjusted up or down for regulating the height oi the liquor in the washer. Any scum and entangled impurities wh ich may rise or collect on the surface of the liquor will be carried by tl i current of liquor intothe overflov-pipc .v and thence into the lower compartment v" and ofi' through a pipe s' into an outlettrap or sealchamber. (Not here shown.)

A manhole X, having a tight-fitting' plate X@ is provided, preferably in the inlet end of the washer-box- Another manhole-opening Y, closed by a tight-litting plate, is also provided in one side of the box, as shown in Figs. 1 and 2. Sight-openings fm, closed by glass plates vl, are provided in the opposite sides of the box, as shown in Fig. Q, for observing the liquor-level and the action of the gas in its passage through the perforated plat-cs of the frames l.

'lhe normal water-line when no gas is passing through the washer is at about the level of the lower edges of the gas-induction channels C; but when gas is being passed through the washer the level ol' the water will be den pressed immediately below the channels C and caused to rise into the intermediate washingchannel F, according to the Volume and pressure of the as ex'lained in my aboveinentioned patent. l."v'hile is passing gas All of the through the induction-channels C, the perforated plates Q', and the crown-plates ll, water or anunoniacal liquor is fed through the pipes through the perforated crown-plate H, so that i y/nI into the washing-channels F and owing to the pressure of the deflected streams of gas passing through the crown-plates is caused to actively flow over the perforations to the dis charge ends of the washing-channels, thence down through the lischarge-pipes N into 'the body of liquor below, and thence up through the supply-pipes O to the upper surfaces of the crown-plates. lt will thus be seen that a continuous circulation of the liquor is maintained, so that it is uniformly brought into Contact with the streams of iurriowing gas, whereby the gas is more perfectlywashcd and the strength of the liquor iu ammonia is greatly increased. The efliciency of the apparatus will therefore be increased.

Having described my invention, what l claim, and desire to secure by Letters atent, isM
